To @ZZ whom t may concern.av v

Be it known that l, JOHN HOWARD MGEL- ROY, a citizen of the UnitedStates, residing at Chicago, in the county of Cook and State ofillinois, have invented certainv new` and -useful improvements inCan-Making Machinery, of which the following is a specification.

My invention is concerned primarily with certain improvements in acan-body machine of the type shown in my application, Serial No.101,838, filed April 7, 1902, which are designed to increase itsefficiency.

My invention is further concerned with a novel automatic feed which canbe applied My invention further consists in a novel attachment which maybe used to increase the output of the machineby making the bodiesoriginally in multiple lengths and ali-- tomatically cutting them intosingle can lengths before they are discharged from the machine.

My invention is nally concerned with a novel attachment by which thebottoms of bakin -powder and similar cans may be attache to the body andthe bead placed therein'before it is discharged from the machine.

To illustrate my invention, l annex hereto seven sheets of drawings, inwhich the same reference characters are used to designate identicalparts in all the figures, of which- Figure 1 is a side elevation. Fig. 2is a top plan view. Fig. 3 is a central vertical longitudinal section.Fig. 4 is a vertical section on the line A A of Fig. 1. Fig. 5 is avertical section on thline B B of Fig. 1.

For lafframework to support the variou elements, l preferably employ abase -piece 20, from which project upward the three standards 21, 22,and 23. The standards 21 and 22 extend higher than the standard 23 andare connected at the top by the longitudinal piece 24, whichextends somedistance beyond the standard 22. The standard 23 is provided at its headwith a crosspiece 25, making the complete standard of a general T shape..The three standards maybe connected by ,the longitudinal pieces 26 and27.

Journaled in suitable bearings in the standards 21 and 22 is thehorizontal driving-shaft 28, which carries the belt-pulley 29, rigidlysecured thereto, and the loose pulley 30. The shaft 28 has securedthereon between its bearings the barrel 31, which l preferably employ asa support for the various actuating-cams with which the machine isprovided, and immediately adjacent the inner bearing is se- 'cured thegear-pinion 32, which meshes with a similar gear-pinion 33,-locatedabove it and rigidly secured on the inner end of the shaft 34, which isournaled in suitable bearings formed in the standards 22 and 23.

Secured to the shaft 34 between the standards 22 and 23, and preferablyimmediately adjacent the standard 22, is the'cylinder 35, which has thegear 36 on its end meshing with the gear-pinion 37 secured on the end ofthe mandrel 38, the gear 36 being twice as large as the gear 37, so thatthe mandrel 38 is rotated twice for each rotation of the drivingshaft 28and the cylinder 35, the arrangement and operation of the mandrel `and.cylinder being the same as that illustrated in the modification of myaforesaid application, where the cylinder is supplied with a pair oftucking blades cooperating with the groove in the mandrel instead of thesingle one shown in the principal form. The cylinder 35 is provided withthe annular fian'ge 39, which cooperates with the correspondinglylocated and sized groove 40 in the mandrel tn insure the two being keptin the proper relative position, the mandrel being journaled uitiinatelyupon the rod or stationary shaft 4.1, which is secured in the standards21 and 22 and which projects a considerable distance beyond the standard22 and furnishes the support for the inner end of the horn 42, which issecured IOS :springing thereto. As best seen in Figs. 5 and 10, themandrel 38 is provided with the straight seaming-groove 43, with whicheoperate alternately the sliding tucking-blades 44 and 45, mounted inthe cylinder 35 and normally held inward therein by the helically-coiledexpanding springs 46, suitably interposed between the blades and thecylinder.

The operation of formin the can may be stated briefly to be that a b ank47 is fed into the proper position to be gripped by the tucking-blade 44and the groove 43, the tuckingblade being forced out at the proper timeby l the contact of its inner edge with the camsurface 48., suitablysupported on the portion 49 of the framework which extendsinto the bodyof the cylinder, which is open. at one end, as best shown in Fi 3. Atthe time the can is being formed t e mandrel is surrounded by the shell50, which extends as far around it as is possible without interferingwith the passage of the cylinder and tuckingblades and is so close tothe periphery of the mandrel as to prevent any possibility of the hookformed on the edge of the blank from out and escaping from the groove inwhich it is formed. As the rotation of the mandrel is continued theblank is wound snugly around it, and its other end at the end of thecomplete rotation overlaps the groove' 43., already containing the hookformed on the other end, far enough so that as it in its turn is engagedby the tucking-blade 45 the seam will be completed in the mannerdescribed in the aforesaid application. At the end of the formation ofthe can the surface 51 of the cylinder which then passes beneath themandrel during its next complete rotation is reduced so that it does notpress against the can, and it is free to be shoved off of the mandrelduring this second rotation onto the horn 42 by the mechanism to bedescribed.

The dischargev meehanism is controlled by the cam-groove 52, formed onthe barrel 31, and which, through the medium of the antifriction-roller53, with which it coperates,

'shoves the cross-head 54 forward and back during a portion of thesecond rotation of the mandrel, the forward movement serving to shovethe can off. The cross-head 54 slides on therod 41V and has projectingfrom the sides thereof the ears 55, in which are secured the rods 56,which extend through the horizontal bearings 57, secured to or formedintegral with the sides of the standard 22. Toward the inner ends ofthese rods 56 are secured the cylindrical ears 58, which support and maybe formed integral with the mutilated cylindrical shell 50, previouslyreferred to. Immediately adjacent the shell 5() are pivoted the fingers59 and 60, the lingers being preferably curved on the same arc as theshell 5() and being preferably providedwith antifriction-rollers 61,which form the surface and engage the edge of the can and force siano itoif of the mandrel. During the formation of the can on the mandrel therollers 61 rest in the groove 40, formed in the surface of the mandrel,which is provided with a pair of helical grooves 62, which are of theproper pitch and properly located so that as the discharge apparatusstarts forward the adjacent ends vof the grooves are directly oppositethe rollers 61, which enter therein and continue therein during theirforward movement, the parts being properly timed for this purpose.

At the end of the discharge movement of the l mechanism the lingers aremoved so as to swing the rollers out of the grooves, thisarrangement-bein necessary in a machine where the mandre rotatescontinuously, as in the form shown. rlhe mechanism for effectin thisresult preferably consists of a pair o guiding-grooves 63 and 64, whichre.- ceive the pins or antifriction-rollers 65 and 66, which projectupward and. outward from the hubs of the fingers 59 and 60. Thesegrooves 63 and 64 are conveniently formed in the lower horizontalportions of a casting 67, which may be secured to the under surface ofthe forward'extension of the piece 24 of the framework. The grooves 63are properly located relative to the lingers so as to cause the rollers6l to be in the plane of the grooves 62 when the pins 65 and 66 are inthe grooves 63. At the end of the outward or discharge movement the pins65 and 66 strike the inclined surfaces 68, which force them into theline of the groove 64, and their possible return` into said groove asthey start to move in theopposite direction is prevented by thespringpressed latches 69, having the beveled faces, by contacting withwhich the pins shove them back until they are passed, after which theyspring in and prevent the return of the pins into that groove. 'As thedischarge mechanism is drawn back the pins 65 and 66 are in the grooves64, and the fingers are held out of engagement with the mandrel, and atthe end of their return movement a similar cam-surface 70 forces themback into the groove 63 against the resistance of a similar spring-latch71. By the mechanism described it will be apparent that as the fingersmove back and forth they are properly controlled for the purposedescribed.

In order to facilitate the discharge of the cans from the mandrel bylessening the friction, I may provide means for contracting the mandrelso as to reduce its effective area in cross-section while the dischargeoccurs but it will be apparent that this mechanism must be arranged sothat the mandrel will have its full cylindrical surface while thecan-body is being formed thereon. For this purpose l form a considerableportion of the surface of the mandrel by the pair of similar wings 72,which are suitably pivoted to the body of the mandrel at 73 and areformed so that Iwhenthey are expanded the out-line of the mandrel IOOIBO

sialic is a perfect cylinder, but the recesses 74 in the body of themandrel in-which the wings swing are of such size and shape as to permitthe Wings to swing inward, as clearly shown in Fig. 10. To cause theWings to swing inward at the proper time, l secure therein the fingers75,', the tips 76 of which extend into the cam-grboves 7 7 formed in theexpanding members 78, which slide in correspondingly-- shaped channelsformed in the body of the mandrel and rotate with the same about the rod41 as a bearing. The slides 78 ,project forward from and are extensionsof the sleeve 79, which extends backward through the bearing in thestandard 22 and terminates in a collar 80, which is embraced so as to bemoved therewith by the cross-head 81, which has the ears 82, throughwhich pass the rods 56, by which the cross-head is guided'.4 Thecross-head is moved outward to contract the mandrel just before thedischarge movement occurs, and immediately after it is moved in theopposite direction, its movement being controlled by the antifrictionroller or lug 83, extending downward therefrom into the cam-groove 84,formed on the surface of the barrel 31. To press the seam thus formed, lemploy the novel mechanism best 'shown in Figs. 1,` 3, and 6 and whichconsists, essentially, of a spring-pressed roller 85, mounted in thecarria e 86, of the shape in cross-section shown in gig. 6, and securedto the inner ends of the rods 56, with which it is moved back and forthlat each operation of the machine. As it is moved outward it does notcome in contact with a can-body; but during its return movement italmost immediately contacts with the can-body which has just beendischarged and presses the seam thereof against the horn 42 as stronglyas may be desired. It will be noted that the roller is so close to'theshell 50, which moves simultaneously therewith, that the can-bodyV4 isseized by the roller before it has .had a chance to escape fram theshell sufficiently to allow the seam to open. 1n order to balance thecarriage and to prevent the pressure on the horn from tending todisplace it and the rod 41, l oppose to the roller a similar roller 87,which, however, is not springpressed, but is journaled in stationarybearings in the carriage, while the roller 85 is journaled in bearingsformed in a yoke 88, which is free to slide in the Ways 89, formed inthe sides of the carriage. A heavy coiled expanding spring is interposedbetween the top of the yoke 88 and the set-screw 91 in the top of thecarria e, by which the tension of the spring is re u ated. To furthersupport the end of the orn and prevent any possibility of bending therod 41, which would disarrange the position of the mandrel,'l: provide apair of tracks 92, formed upon the portion 93 of the frame, and Ijournal -upon the bottom of the carriage the rollers 94, which travel onthe ways 92'. To carry the canbodies thus formed With their seamspressed along the horn 42, which may be4 rovided with the customaryfluxing and sol ering attachments, if that kind of cans is to be made, lsecure to the sides of the carriage 86 a pair of bars 95, which may beconveniently formed of strips ofangle-,iron and which virtuallyconstitute -extensions of the' rods 56. At their outer ends and atintermediate points, if the horn is very long, l locate one` or morepairs of rollers 96, upon which the angle-bars 95 are supported'. Theserollers are conveniently supported by the pins 97, secured in the ears98, formed or secured in the channelbars 99, which are supported attheir outer ends on the cross-piece 25 of the standard 23, and one ofthem is supported at its inner end from a bracket 100, extending outfrom the side of the standard 22. rlhe other one is supportedat itsinner end on a bracket 101`, projecting outward from the side 102 of theblank-feeding mechanism, to be described. The bars 95 have suitablylocated on their upper surfaces the yielding spring ressed pawls 103,the noses of which trave in the channels 104, formed in the sides of thehorn 42 and serve to advance the cans along the horn in the manner wellknown in this class of devices. The i'it of the cans on the horn is-snug enough to prevent their moving backward from the friction of thepawls 103, as their springs are weak. The can-bodies thus formed may be,if desired, fluxed and soldered on the horn and then discharged,therefrom Without any further operation. l contemplate, however,increasing the capacity of the machine by making the can-bodies of adouble or triple length and providing mechanism at the end of the hornfor cutting them into single lengths. For this purpose l provide themechanism best shown in Fi s. 1, 2, 3, 7, and 8, where it Will be seen tat the shaft 34 is extended beyond its bearing in the lstandard 23 andhas on its outer end the camldisk 105 and sprocket wheel 106. Journaledin bearings 107 and 108, formed on the outer end ofthe horn 42, is theshaft 109, which carries the cylinder 110', which is provided With oneor more cutting-disks 1 1 1, depending on how many parts the singlecylnder is to be cut ,into. A bevelear pinion 112 is secured to theouter end o the shaft 109, and coperating with the cylinder 110 andshearing-disk 1 1 1 is asimilar cylinder 113 and shearing disk 114,which are mounted upon the shaft 115 journaled in the bearingsA 116 and117, formed on the ends of the arms v 118 and 119 of a frame which ispivoted in a bearing 120, secured on the side of one, of thechannel-bars 99. This frame has an arm 121 (best shown in Fig. 8)extending downward beneath the shaft 34 and provided with anantifriction-roller 122, which coperates with the cam 105. Secured onthe shaft 1 15 outside of IOO IIO

. der 138, slight the bearing 117 is a small sprocket-wheel 123, whichis driven from the sprocket-wheel 106 by means of the sprocket-chain124, which is guided and positioned by the sprocket-wheel 125 and 126,suitably mounted on bearings 'supported by the channel-bars 99. Achaintightener 127, mounted upon the arm 128, Serves to keep the chaintaut during the operationl of the apparatus and to permit ofthe framebeing swung up to separate the rollers when the can is being discharged.Adjacent the sprocket-wheel 123 is the bevel-gear pinion 129, whichmeshes with the double-faced sprocket wheel 130, which is journaled inbearings 131 and 132, supported from the arm 133, extending from thecylinder-supporting frame. Projecting downward from the under surface ofthe bearings 116 and 117 is a pair of cam-fingers 134 and 135 ,whichserve to accurately position the last can which has been delivered priorto the engagement of the cutting-disks with the tin. The operative faceof the cam 105 is abrupt, so that the cuttingdisks are brought togetherwith suicient force to sever the can at the point of contact, and as thedisks arerotated in unison through the mechanism described theircontinued rotation serves to cut the can-cylinder into the two or morelengths providedfor. When the cutting iscompleted, the frame carryingthe cylinder 113 is swung up under the stress of the strong coiledIcontractile spring 136, connecting one of the channel-bars 99 and thearm 121 thus permitting the discharge of the severed sections, thedouble bevel-gear 130 and its bearing 132 being raised out of the way ofthe sections, which are discharged the same as if they were a singlecan-body.

In case it is desired to use the machine for manufacturing baking powderand similar cans, in which the bottom is merely crimped on and notsoldered and the can-body'is rovided with a bead, I add the mechanism ilustrated in Figs. 17, 18, and 19, where it will be seen that the horn42 terminates in a reduced portion 137, upon which is journaled arcylinysmaller in diameterthan the horn and preferably having theroller-bearings 139, so that it may rotate with perfect freedom. In thisconstruction the cam-disk 105HL and the sprocket-wheel 106a are securedon the end of the shaft 34 and are similar to the cam-disk 105 andsprocket-wheel 106, eX- cept as theyl are necessarily modified for thepurpose of the present mechanism. Similar bearings 116a and '117%carried by similar arms 118a and 119g, have the shaft 115ajournaled-therein and provided with the beading-roller 140 and thecrimpin -roller 141, the shaft havin further secure thereon the sprocketwhee 1232, connected with the sprocket wheel 106a by the sprocket chain124a. On the outer end of the shaft a gearpinion 129a is secured andwhen the frame is lowered meshes with a gear-pinion 112, which issecured on the end of the short shaft 109a, journaled in a bearing 142,preferably formed with the antifriction -i rollers 143, formed in thecarriage 144, which is secured to and moves with the outer ends of theangle-iron bars 95. The inner end of the shaft 109a is provided with thechuck 145, suitably shaped to engage the can-bottom 146, which isdropped into the hood 147, forming the upper portion of the carriage144, through the aperture 148 in the upper surface thereof. The supplyof can-'bottomsis furnished by the chute 149, whose interior dimensionsare of the proper size to permit a single line of can-bottoms to ,occupyit, the bottom of the chute being normally closed by the gravitydetent150, having the ledge 1-51 normally standing beneath the bottom thereof,but adapted to be contacted by the end of the carriage as it is movedback to the dotted-line position of Fig. 19 and swung back so as to Ipermit of a single can-bottom being dropped through the aperture 148into the hood. The lip 152 of the hood is sufficient to prevent theuncrimped bottom from escaping, and as the carriage 144 is moved back tothe full-line position the bottom is properly pushed onto the can bodyon the cylinder 138 prior to the descent of the frame. As the framedescends howeverfthe crimping roller 141, rotating rapidly andcoperating with the rotating canbody and bottom, serves to crimp thelatter into position, and at the same time the beading-roller 140,coperating with the beading-flange 153, serves to form the bead in themanner customary with this class of devices. the dotted-line position,the pair of prongs 154, penetrating oppositely-located apertures 155 inthe chute 149, serve tol prevent the descent of another can-bottom untilthe carriage is retracted. It will be observed that the extended end ofthe rod 34 serves asa guide for the movement of the carriage 144.

To feed the blanks to the machine, I preferably employ the feedingapparatus best IOO When the detent 151 is swung into l shown in F s. 1,2, 4 to 7, and 9. The blanks are receive on a feed-table 156, having auiding ledge or flange 157, against which the lanks are carried andpositioned by the rollers 158, carried by the forked lever 159, havingthe hub 160, by which it is j ournaled ,on

the frame, and-provided with the arm 161,

having a bearing-surface, preferably an antifriction-roller 162,'engaging withy the cam Y siento through which thespring 170 acts toreturn the slide 164 to its outward position after it has been movedinward by the action of the cam 171, cooperating with theantifrictionroller 172 on the arm 173, secured to the shaft 167. Thefeeding mechanism thus far described, which is not automatic, is thesame as that shown in my aforesaid application, Serial No. 101,838.

' To deliver the blanks one by one automatically to the table 156, lprovide the sliding rod or bar 174, which is mounted to slide in thebearings 175 and 176, su ported by the brackets 177 and 178, secure onthe standards 21 and 22, respectively. The rod 174 is provided withtheprojection, preferably an antifriction-roller, 179, which,cooperating with the cam-groove 180 on ,the barrel 31, serves toreciprocate the bar 174 once at each operation of the machine.' The bar174 has secured on its inner end the cross-head 181, which has theplurality of elongated fingers 182 secured thereto, extending throughapertures in the ledge 157 andv sliding in correspondinglysha ed,referably dovetailed, channels forme in t e surface of the table 156.Their'outer ends are provided with the hooks 183, which engage and drawthe blanks one by one onto the table as they are delivered to thefingers by the mechanism to be described.

Referring now especially to Figs. 6, 7, and 9, the blank-holder is of agenerally rectangular shape and formed by the front wall 102, rear wall184, the inner side wall 185, and

outer side wall 186, a portion 'of which is in l the form of a door 187,which can be swung down in reloading theholder. The blanks are supportedupon a carriage 188, having the horizontal cross-piece 189 and the pairsof elongated downwardly-proj ecting ears 1 90, between which arejournaled the pairs of antifriction-rollers 191, which rest against theedges of the wall 102 as the carriage moves u and down in the holder. Toautomatica y raise the blanks without the employment -ofany mechanicalactuating mechanism, I

' provide a counterbalance mechanism, wliich consists of a pair ofsprocket chains 192, which `are secured at one end to the carriage andwhich extend up over a pair of sprocketwheels 193, secured on the shaft194, journaled in the bearings 195 and `196, projecting vforward frombrackets secured on' the'front wall 102. Secured to the end of the shaft194 immediatel adjacent the inner wall 185 is the frictionisk 197, withwhich coperl ates the friction or brake lever 198, pivoted at 199 toastud on the wall 185 or to the portion 93 of the frame. The free end ofthe lever 198 is turned inward and stands in the plane of the cam 200,secured on the shaft 34 and shaped and located so as to force the lelver 198 down on the disk 197 with sufficient force-t0' prevent anymovement of the blank during a certain period of the operation of themachine. Secured to the other ends of the chains 192 is the weight 201,which in the form of mechanism shown is equal in weight to one-half ofthe weight of the blanks when the apparatus is completely loaded.Secured to another pair of chains 202, which are connected at theirupper ends to the weight 201 and at their other ends to the carriage188, is another set of weights 203, preferably in the form of heavymetal cylinders, whose combined wieghts are equal to the weight of theweight 201, the total combined weights opposed to 'the blanks beingequal to their weight and sufficient more to overcome the inertia of theapparatus and slightly overbalance the same, so that the blanks alwaystend to rise. ,As the blanks are taken off it will be a parent thattheir weight decreases, and the ordinary construction of acounterbalance were employed, as the supply of blanks diminished theywould become very much overbalanced and the upward pressure would becometoogreat, and for this reason l employ an automatic compensatingarrangement, as shownI which compensates for the loss of the blanks byswinging a portion of the weight, that of the weights 203, from -oneside of the balance to the other, so that the pressure tending to raisethe blanks is kept substantially uniform no matter what number of themare removed. ,The overbalanced mechanism shown serves to press theblanks upward and yagainst the under surface of the fingers 182,

wchen they are over the pile, and when they are withdrawn from the pilethe cam 200, acting on the arm 198 and friction-disk 197, prevents` thefurther upward movement of the supply of blanks, which is thus regulatedautomatically. Any desired form or separating mechanism to disengage thetopmost blank from the others maybe employed in connection with themechanism thus shown for keeping the blanks at the proper level but lpreferably ,employ the extremely simple mechanism shown, whereasupporting-rod or rock-shaft 204 is mounted in bearings formed in thebrackets 205 and has pivoted thereon the supporting-arm 206, whichcarries the barl 207, extending over the to s of the blanks and which suports the li ters,

which may be of any desire form, pneumatic ICS which has been raised bythe hook of the finer, upon which it rests, drops and permits theifte-rs to drop'upon the uppermost blank, which adheres thereto. As thefingers return the hook raises the antifriction-roller and is pulled offof the llfters as the fingers are drawn toward the table 156 to depositthe blank thereon.

To facilitate the raising of the weights 201 and 203 when the apparatusis to be recharged, I secure on the end of the shaft 194 a ratchet-wheel2 1 0 with which adet'ent-pawl 211 may be thrown into engagement when itis to be used. A lever 212 is hung on the -end of the shaft and has thespring-pressed pawl 213 thereon, which can be swung into engagement-withthe ratchet-wheel, and by the use of the lever the necessary power canbe a plied to the shaft 194 to rotate it to raise t e weiglhts; lowerthe carriage, and ermit. a fres supply of blanks bein placed t ereon.

As similar devices have (been constructed, no provision has been madefor supplying blanks to the machine as it is being recharged, and forthis purpose I providewhat may be called an auxiliary feed, whichconsists of a rod 214, adapted to slide through vertical bearings 215and 216, lsupported bythe yoke 217, secured to or formin a continuationof the front wall1,02`.of the b ank-chamber. In-

terposed between an adjustable nut 218 on the top of the rod 214 and the'bearing 215 is the helically coiled expanding spring 2 1 9,

which tends to hold the rod 214 upward. The lower end of the rod.214, asseen in Fig.

9, has the beveled face 220 and the recess 221,

The operation of this auxiliary feed Will be readilyapparent. When the supply of blanks is nearly exhausted, the parts beingin,

the position shown in Fig. 9, thefattendant presses down the rod 214against the resistance of its Vspring until it engages with and fastensitself to the supporting-fingers 223, the tension of the spring beingadjusted, so that it holds the remaining blanks pressed upwardv withabout the 'same force a's. the regular mechanism. The remaining blanksbeingl thus supported,l it will be apparent that the attendant can nowproceed to the rechargin of the machine without interfering at allwitigl the operation thereof.

When the supply of blanks is exhausted, if the attendant `should be awayfrom the machine it is `desirable to stop it and preferably to sound'analarm, 'and for the purpose of stoppingit I employ the mechanism bestshown in Figs. 1, 2, 4, and 14, whereit will be stopping the machine.

Securedon the rod 174 is the lug 227, whose inward face is vertical, while itsoutward face 'is inclined. Mounted on the rod .225 .is the latch 228,whose vertical arm. 229 in its operative position rests against -the end230 of the core 231 of a` solenoid 232, which is sup orted on thebracket 175. The reduced en 230is immediately adjacent an inclinedsurface 233, which, as the solenoid is energized and the core drawninward, serves to tilt the latch 229 over to the dotted-line position ofFig.

While I have shown and described my invention asembodied in astructurein which a tucking-blade movable in a'cylinder is em ployed, Ido not desire the claims to be interprete'd as limited to a movabletucking-blade,

as I contemplate employing a stationaryone. 4

Furthermore, while I have'shown and described a cylindrical mandrel, -itwill be obvi- Y ous that a truncated conical one might be em` ployed, inwhich case the cooperating c llnder would also be of a truncate conicalorm or .the mandrel mi ht be square, rectangular, pressed latch 222,secured in the end of the elliptical, or ova or 'other irregular shapein cross-section, and straight or pyramidal, as desired, -in which casethe coperating face of the cylinder would be quadrilobate,e liptical,with its major axis transverse to the major IOO axis of the mandrel, orin general of a shape, 4

such that the surfaces of the mandrel and cylinderwill be engaged(except for the thickness of the blank) during the forming rotation ofthe mandrel. Consequently when Imention a cylinderin the claims ascooperating with the mandrel it will be understood that I do not desireto be limited to a true cylinder, but onlyl to a'surface .ofthenecessary sha e to cooperate in the manner described Wit the mandrel. If

While I have .shown AandI described my improvements and inventions inthe form carryout their purposes, it will be understood which I atpresent consider best adapted to that they are capable of modifications,and, L
